The key provided by the invention has the advantage that the key structure is convenient to detach. In addition, the key upper shell which is easy to damage is frequently pressed, so that the key upper shell is easy and quick to assemble and disassemble, and the key upper shell is convenient to replace and maintain. The whole structure of the key is screwless, and no special tool is needed for replacement and maintenance. The whole structure is simple, the parts are fewer, the production and assembly process can be simplified, and the production cost is reduced.
A key as shown in fig. 1 to 4 includes a key lower case 1, a key upper case 2, a moving tray 3, a slide arm 4, and a slide pin 5.
The key lower case 1 has a hollow structure with an upper opening, and the hollow portion may be used to accommodate part or all of the components of the key. The hollow structure may be a stepped hollow cylindrical structure as shown in fig. 3, and in other embodiments, may be a hollow cuboid, a regular polygon, or some special-shaped structure, which is not limited in this application. A first slide pin hole 12 is provided on the lower case side wall 11 enclosing a hollow structure, and the first slide pin hole 12 penetrates through the lower case side wall 11 so that the hollow portion of the key lower case 1 can communicate with the outside through the first slide pin hole 12.
The key top case 2 has a hollow structure with an opening at the lower portion, and as described above, the specific shape of the key top case 2 is not limited in this application. The second sliding pin hole 22 is provided on the upper case side wall 21 surrounding the hollow portion of the key upper case 2, and the second sliding pin hole 22 may or may not penetrate through the upper case side wall 21, which is not limited in this application.
The key upper shell 2 is sleeved on the key lower shell 1, namely the key upper shell 2 is sleeved on the lower shell side wall 11 of the key lower shell 1 through a lower opening. The second slide pin hole 22 is opposite to the first slide pin hole 12 so that the second slide pin hole 22 can communicate with the inside of the key lower case 1 through the first slide pin hole 12.
As will be appreciated by those skilled in the art, the key upper case 2 and its lower opening may be shaped and sized as shown in fig. 3 to correspond to the key lower case 1, and the inner diameter of the lower opening is equal to the outer diameter of the lower case side wall 11 of the key lower case 1, so that the key upper case is advantageous for cooperation and compact structure; however, in a different embodiment, it is not necessary to correspond to the above, for example, if the key lower case 1 shown in fig. 1 is a hollow cylindrical structure with a constant shape or a stepped shape, and when the key upper case has a square structure, the lower opening of the key upper case has a square shape, and the side of the square shape is longer than the diameter of the key lower case 1, the key upper case may also be sleeved on the key lower case 1, and the present invention may also be implemented. The different shapes of the key top case 2 facilitate personalized customization, and thus, the present application does not limit that the shapes of the key bottom case 1 and the key top case 2 must correspond.
The moving tray 3 is located at an intermediate position within the key lower case 1. The movable tray 3 is movable up and down with respect to the key, upward, i.e., in the direction of the key upper case 2, and downward, i.e., in the direction of the key lower case 1.
One end of the sliding arm 4 is rotatably connected with the movable tray 3. The rotation connection can be the cooperation of rotation axis and rotation hole, and rotation axis and rotation hole set up respectively on two parts that are connected to insert the rotation hole with rotating the taking out, form rotation connection relation. The slide arm 4 is rotatable with respect to the movable tray 3. One end of the sliding arm 4 can be rotationally connected with the edge of the movable tray 3, so that the size of the movable tray 3 is reduced, and the weight of keys is reduced; and, also be convenient for installation and connection.
The sliding pin 5 is located in the key lower case 1, and one end of the sliding pin 5 is rotatably connected with the other end of the sliding arm 4 away from the movable tray 3. The other end of the sliding pin 5 passes through the first sliding pin hole 12 and extends into the second sliding pin hole 22, so that the key upper case 2 is prevented from moving up and down relative to the key lower case 1, and cannot be completely separated from each other. For example, when the hole inner diameter of the second slide pin hole 22, the hole inner diameter of the first slide pin hole 12, and the outer diameter of the slide pin 5 are identical, the movement of the key upper case 2 in the up-down direction with respect to the key lower case 1 can be completely locked due to the obstruction of the slide pin 5; the movement of the key top case 2 in the horizontal direction with respect to the key bottom case 1 may be achieved by the inner diameter of the lower opening of the key top case 2 being equal to the outer diameter of the bottom case side wall 11 of the key bottom case 1, or by structural limitation of the key top case 2 and the key bottom case 1 in the application scene of the key, so that the key bottom case 1 and the key top case 2 form a whole, and when the key top case 2 is pressed, the key bottom case 1 is also pressed therewith.
When the movable tray 3 moves up or down with respect to the key lower case 1. Because both ends of the slide arm 4 are rotatably connected to the moving tray 3 and the slide pin 5, respectively, for example, the rotatably connected slide arm 4 may be rotated clockwise or counterclockwise with respect to the moving tray 3 and the slide pin 5 as in the embodiment shown in fig. 2. So that the included angle between the sliding arm 4 and the horizontal direction is larger and larger along with the upward or downward movement of the moving tray 3, since the moving tray 3 moves up and down only relative to the key lower case 1, the length of the sliding arm 4 is fixed, and then according to the pythagorean theorem, the sliding arm 4 will necessarily apply a force to the sliding pin 5 along the sliding arm to move the tray 3, the force is decomposed into a force in the up and down direction and a force in the horizontal direction, the upward and downward movement of the sliding pin 5 is blocked by the first sliding pin 12, the force in the up and down direction is blocked and counteracted, and the force in the horizontal direction can drive the sliding pin 5 to slide along the first sliding pin 12 to the inside of the key lower case 1. The first sliding pin hole 12 provides a passage for the extension and retraction of the sliding pin 5, and on the other hand, has a limiting and guiding function, and guides the sliding pin to slide along the opening direction of the first sliding pin hole 12 without deviation. When the sliding pin 5 is retracted to the first sliding pin 12 and separated from the second sliding pin hole 22, the key upper case 2 and the key lower case 1 can be separated, and operations such as replacement and maintenance can be performed simply and quickly. The same principle can be adopted to realize the assembly of the key upper shell 2 and the key lower shell 1 by reversely converting the process. The whole structure of the key is screwless, and special tools such as screwdrivers are not needed for replacing and maintaining the upper shell of the key.
In different embodiments, the movable tray 3 moves up or down relative to the key lower case 1, which may be that the movable tray 3 is made of magnetic material, the south pole or the north pole of the magnetic field faces the key upper case 2 and faces the key upper case 4, and the movable tray 3 can be driven to move up or down by attraction or repulsion of a magnet on the upper part of the key upper case 2; the movable tray 3 may be made of a metal material that can be attracted by a magnet, and the movable tray 3 may be driven to move upward by attraction of a magnet on the upper portion of the key upper case 2, and the movable tray may be moved downward by gravity or other structural means after the magnet is removed.
Alternatively, as shown in fig. 2 and 5, the slide arm 4 includes a slide upper arm 41, a slide lower arm 42, and a return piece 43. The sliding arm 4 has one end being a sliding upper arm 41 and the other end being a sliding lower arm 42, the sliding upper arm 41 being slidably engaged with the sliding lower arm 42, and the sliding arm 4 can maintain sufficient rigidity when the moving tray 3 moves upward or downward, and deformation such as bending does not occur, so that the sliding pin 5 cannot be provided with an acting force or an acting force direction change. Both ends of the return piece 43 are connected to one ends of the slide upper arm 41 and the slide lower arm 42, respectively. The ends of the sliding upper arm 41 and the sliding lower arm 42 connected to the restoring member 43 are referred to as restoring ends, and the opposite ends are connecting ends. The positional relationship between the slide upper arm 41 and the slide lower arm 42 may be set to a preset value, and the reset piece 43 is configured to provide a reset driving force for bringing the reset ends thereof closer to each other when the slide upper arm 41 and the slide lower arm 42 are away from each other with respect to the preset value. In some embodiments, the reset member 43 may be further configured to provide a reset driving force to move the reset ends thereof away from each other when the sliding upper arm 41 and the sliding lower arm 42 are moved closer to each other with respect to a preset value. It will be appreciated by those skilled in the art that only the return member 43 may be provided to always provide a driving force to bring them closer to each other when a preset value, i.e., a minimum distance between the slide upper arm 41 and the slide lower arm 42, is set. Through setting up of piece 43 resets, can effectively provide the buffering to removal tray 3 and slide pin 5 when upwards or down removing to removal tray 3, avoid rotating connection structure and take place to damage.
Alternatively, as shown in fig. 2 and 5, one end of the sliding upper arm 41 and/or the sliding lower arm 42, which is not rotatably connected, i.e., the reset end, is a hollow cylindrical structure with an opening on the end surface, and the opposite end of the sliding arm 4 can be sleeved to form a sliding sleeve, so that the sliding upper arm 41 and the sliding lower arm 42 can slide relatively, and the sliding direction can be guided and limited. For example, when the reset end of the sliding upper arm 41 is of a hollow cylindrical structure, the reset end of the sliding lower arm 42 is of a cylindrical or hollow cylinder, and the inner diameter of the reset end of the sliding upper arm 41 is equal to the outer diameter of the reset end of the sliding lower arm 42, so as to form a sliding sleeve. In other embodiments, the reset terminal may have another structure such as a hollow rectangular parallelepiped, and the present application is not limited thereto.
Alternatively, as shown in fig. 2 and 5, the restoring member 43 is a first elastic member. The elastic piece can be elastic structures or materials such as a spring and a silica gel column, can deform under the action of external force, and can recover the original size and shape after the external force is removed. The reset member 43 is disposed in the hollow cylindrical structure, and has both ends connected to the sliding upper arm 41 and the sliding lower arm 42, respectively, and is capable of providing opposite driving force to reset the sliding upper arm 41 and the sliding lower arm 42 when they slide relatively. It will be appreciated that in the preset position of the sliding upper arm 41 and the sliding lower arm 42, the sliding pin 5 locks the key upper case 2 and the key lower case 1, and the restoring member 43 is in a state of no external force, i.e., neither compressed nor relaxed.
Optionally, as shown in fig. 2, the key further includes a magnet 31, where the magnet 31 is disposed on the movable tray 3 and is fixedly connected with the movable tray 3, and a south pole or a north pole of a magnetic field of the magnet 31 faces the key upper case 2, and the magnet 31 may be opposite to the key upper case 4. At this time, the movable tray 3 may be made of a light material such as plastic, so that the weight of the key can be reduced, and the production cost of the key can be reduced. The magnet 31 and the movable tray 3 can be fixed by bonding or embedding, etc., so that the magnet 31 and the movable tray 3 are fixed into a whole structure, and the magnet 31 can drive the movable tray 3 to move together when being attracted or repelled.
Alternatively, as shown in fig. 2, when the movable tray 3, the slide arm 4, and the slide pin 5 are in the normal state of the lock key upper case 2 and the key lower case 1, each are in the horizontal position, and the sliding direction of the slide pin 5 is perpendicular to the moving direction of the movable tray 3. Assuming that the sliding pin 5 slides inward of the back of the key lower case 1 by a distance D1 and the moving tray 3 moves upward or downward by a distance D2, the moving tray 3 moves to drive the angle between the sliding arm and the horizontal plane to be θ, d1=d2/tan θ in an ideal state.
Alternatively, the movable tray 3 may be placed on the lower surface of the middle position in the key lower case 1 at the time of installation, or as shown in fig. 3, a protrusion 14 is provided for placing the movable tray 3, and at this time, the movable tray 3 can slide out of the second slide pin hole 22 by moving upward only the slide pin 5, but the installation is simple, and the production cost can be reduced. A reinforcing rib or other structure may be provided between the boss 14 and the lower case side wall 11 to strengthen the overall strength of the key lower case 1.
Optionally, as shown in fig. 6, a second elastic member 24 may be further included in the key. The second elastic piece 24 is located between the movable tray 3 and the key upper shell 2, two ends of the second elastic piece 24 respectively support against the movable tray and the key upper shell, downward force is applied to the movable tray 3 or the second elastic piece is in a state of not applying elastic force, so that the movable tray 3 is prevented from moving upwards relative to the key lower shell 1 due to sliding in the using process of the key, locking between the key lower shell 1 and the key upper shell 2 is accidentally released, accidental falling of the key upper shell 2 is caused, and stability of the key is affected. In the disassembly process, the upward movement acting force applied to the movable tray 3 by the magnetic force is larger than the elastic force of the second elastic piece 24, so that the disassembly of the key upper shell 2 can be realized.
Alternatively, as shown in fig. 2, the cross section in the opening direction of the second slide pin hole 22 is smaller than the cross section in the opening direction of the first slide pin hole 12. The cross sections of the sliding pins 5 also correspond to the cross sections, respectively, and the cross section in the opening direction of the part of the sliding pin 5 extending into the second sliding pin hole 22 is smaller than the cross section in the opening direction of the part of the sliding pin 5 located in the first sliding pin hole 12, so that wedge-shaped limiting is formed on the sliding pin 5, and the distance of the sliding pin 5 extending outwards from the first sliding pin hole 12 is limited. In various embodiments, the cross-section of the second slide pin hole 22 may be equal to the cross-section of the first slide pin hole 12 in the direction of the opening; the present application is not limited thereto as long as the technical scheme of the present application can be implemented. It will be appreciated by those skilled in the art that the cross-sections of the second slide pin hole 22 and the first slide pin hole 12 in the direction of the opening do not have to be circular, but may be rectangular, elliptical, or polygonal.
Optionally, as shown in fig. 2, a limiting post 23 extending towards the key lower case 1 is disposed on the key upper case 2, the limiting post 23 is opposite to the movable tray 3, and limits the maximum distance of the movable tray 3 moving upwards relative to the key lower case 1, so as to prevent the movable tray 3 from moving upwards too much, and the sliding pin 5 slides out from the first sliding pin hole 12, thereby increasing the difficulty in installation. On the other hand, the second elastic piece 24 can be sleeved on the limiting column 23, because the second elastic piece 24 is not fixedly connected with the movable tray 3 and the key upper shell 2 respectively, the limiting column 23 can play a role in guiding the compression deformation of the second elastic piece 24, so that the second elastic piece 24 is prevented from deforming to the horizontal direction when being subjected to pressure, and then is deviated from a preset position, and the stability of the key is reduced.
Optionally, as shown in fig. 2 and 3, the lower part of the key lower case 1 is provided with a bearing platform 13, the bearing platform 13 is located below the first sliding pin hole 12 and extends to the outer side of the key lower case 1 in the horizontal direction, and the upper case side wall 21 of the key upper case 2 is buckled on the bearing platform 13, so that when the key upper case 2 is installed, the first sliding pin hole 12 and the second sliding pin hole 22 are located on the same plane, and installation is facilitated.
Optionally, as shown in fig. 2, a plurality of sliding pins 5 are included in the key. The other first slide pin holes 12, second slide pin holes 22, and slide arms 4 are in one-to-one correspondence with the slide pins 5, and can lock the key lower case 1 and the key upper case 2 from a plurality of directions.
